Dou Yi left the palace and did not go back to his prime minister's residence. Instead, he came to the home of his second brother Dou Yan.
Upon learning that his brother had arrived, Dou Yan happily went out to greet him: "Brother!"
Dou Yujun had a strict upbringing, and the five Dou brothers were brothers. They loved and respected each other.
Dou Yi took her second brother's hand, strode inside and said, "Go and say hello to your father first! We'll talk about it later..."
Dou Yan paused and said awkwardly, "Brother, let's go. My father just kicked my brother out, so I won't make him angry."
Dou Yi looked surprised and said even more curiously: "My father loves you the most, why would he be angry with you?"
Dou Yan said, "I'll talk to my brother about this later. Brother, let's go and pay my respects to my father. I'll ask my wife to prepare some side dishes to go with the wine. You and I can talk about it in detail. It just so happens that I have something to ask my brother for advice here."
"Okay!" Dou Yi strode towards Dou Yujun's yard, but she was thinking about what happened.
The five brothers are all disciples of Confucianism. They were influenced by their father. The five sons were admitted to the imperial examination. They are all Confucian scholars, but their minds are good in different directions. These two brothers are open-minded, fond of virtues and good deeds, and are proficient in rituals and music. They are the closest to their father Dou Yujun when he was young.
Similar. Six years ago, for some reason, Dou Yujun hoped that one of them would withdraw from officialdom and help him manage Kaifeng University.
Dou Yan was the first to give up his official position and take on this important task.
Dou Yi admired this move very much.
You must know that although his second brother did not serve as prime minister for as many years as he did, he still held the position of minister of the Ministry of Rites and compiled 120 volumes of "Yu Zhengyue". All the rituals and music of the new dynasty were written by his younger brother.
Dou Yi asked herself that she could not compare with this kind of spirit.
Of course, while I admire you, I also have a little regret.
When outsiders talk about the Five Dragons of the Dou family, most of them praise them, saying that the fifth son passed the imperial examination and the family is full of heroes. But as the eldest brother, Dou Yi knows that although the brothers are all Jinshi, when it comes to talent and potential, Sanlang, Shilang, and Wulang
There is no way to compare with myself and Erlang.
In the past, Feng Dao also commented on the five sons of the Dou family, and Dou Yi and Dou Yan were particularly talented.
Dou Yan is fully capable of becoming a prime minister. It will be such an honor to have one disciple, two prime ministers, and five advanced scholars.
Dou Yi felt sorry every time she thought about her second brother.
Dou Yi came to her father's yard and asked her servants to inform her.
Originally, it was the eldest brother's duty to take care of his father. After his brothers grew up and separated, Dou Yujun continued to live with him. This was because Dou Yan retired from officialdom and took over Kaifeng University, so Dou Yujun went to live with Dou Yan himself.
Dou Yi felt very unhappy about not being able to fulfill her filial piety.
Dou Yi greeted Dou Yujun with questions.
Dou Yujun is already ninety years old, and his health is not as good as before. He has taken on the title of Prince and Tutor and is in a state of semi-retirement.
Seeing that her father didn't seem angry, Dou Yi said hello, chatted a little about the family affairs, and asked about Dou Yan. As the eldest brother, he should be a peacemaker and mediate the conflict.
When Dou Yujun saw his son asking, he shook his head and said, "As a father, I am not angry with Erlang. It's just that I can't live with it. I'm old and useless. I can't be as open-minded as you." He waved his hand and said, "Go down.
Let's talk to Erlang and we will understand." He suddenly smiled and said, "Don't get angry."
Dou Yi was filled with doubts, bowed and left.
When they came to the living room, Dou Yan had already prepared food and wine and invited Dou Yi to take a seat.
The two brothers drank three glasses of each other, and Dou Yi first asked about his doubts.
Dou Yan smiled guiltily and said, "Brother, let me talk first. This matter is a bit big. I'm afraid it will make my brother unhappy and delay his affairs."
Dou Yi burst into laughter and said, "It seems like it's not a big deal?" He didn't refuse, and basically told what happened after Luo Youdu left him here today.
Dou Yi thought that after hearing her words, his second brother would have a solemn expression, but what he didn't want to see was a pair of shining eyes.
Dou Yi thought for a moment that her younger brother had not responded, and said: "Your Majesty,
He emphasized that the great scholar Chu Yan and the monk Huai Bing had jointly studied physics. His majesty said that he planned to promote it in schools. What the second brother didn’t know was that this physics had broken away from the teachings of Confucius and Mencius, and the prospects of physics were no longer
It’s about making people understand but it’s about war.”
Dou Yan pondered for a moment and said, "Brother, I don't dare to agree with what I said."
Dou Yi said in a fierce tone: "That's because you don't understand physics. There are some things that I can't tell you, but physics is really going to develop. Brother Wei has a premonition that is very, very scary."
As the prime minister of the Yu Dynasty, Dou Yi naturally understood many things.
In fact, the physics developed by Chu Yan, a master of mathematics, Monk Huai Bing, a mechanics expert, and Hulasd, the Manichaean treasure tree king, is not on the same level as the physics of later generations. It is at best an introduction to elementary physics. But
This introduction only involves the knowledge of various force parabolas.
Under Luo Youdu's constant reminders, various artillery-rock carts have specified weights and measures, unified standard accessories, and specified the weight and density of ammunition, which facilitates assembly line production, facilitates quick maintenance, disassembly and transportation on the battlefield, and has also made great progress in accuracy.
of improvement.
Through the advancement of mechanics, the trebuchets of the Dayu court are now able to launch boulders weighing 150 kilograms.
In addition, Dayu's gunpowder also had an innovation. Once, someone accidentally mixed a little sugar into the black gunpowder. As a result, the power was greatly increased, and the thunderbolt bullets also had a certain power, no longer the thunder was loud and the rain was small.
Dou Yi saw all this and was a little scared.
If all this was used as a secret weapon for the Yu court, Dou Yi would not be pedantic and fearful, but Luo Youdu's attitude would promote some of the knowledge and promote it in universities.
This made Dou Yi a little scared.
He watched the black powder develop from a little bit as powerful as fireworks to now cracking mountains and cracking rocks. In the future, there is no guarantee that it will be able to blow people to pieces...
Dou Yan looked surprised and said: "How terrible can it be? It can be compared to when Yelu Deguang came to Kaifeng and the general asked him for a reward. His words were: 'We, the Khitan, have no precedent of rewarding the army like this. If you want money, you can do it yourself.
Let's go to the grass valley, and it will be even more brutal?"
Dou Yi's face turned pale, and in front of his eyes was the scene of ferocious Khitan soldiers plowing grass and grain around the capital in Kaifeng City. If it were not for Feng Dao's blessing, the entire Dou family might have died in that military rebellion.
He came back to his senses and looked at Dou Yan blankly.
Dou Yan continued: "Brother, shouldn't we be glad that the terrible power you mentioned is in our hands and not on the side of our enemies?"
There was a trace of confusion in Dou Yi's eyes, and she said: "It is true to say so, but now the world is settled. It is time for the people who have suffered for hundreds of years to live a good life..."
Dou Yan said: "Isn't this what my brother has been doing all these years? Since the founding of the Yu Dynasty, my brother has held the imperial seal to this day. Your Majesty's trust in your brother is no less than that of Emperor Zhaolie and Kong Ming, or Emperor Taizong and Fang Xuanling.
"
Dou Yi nodded silently and said, "It is true. I will have no regrets in my life as a brother if I can meet His Majesty." He was a little confused, waved his hand with a bit of irritation and said, "It's just that you don't think you can teach in a school where you educate people."
Are these inappropriate?"
Dou Yan looked at Dou Yi seriously and said solemnly: "If I don't hide it from my brother, I think it is acceptable." Dou Yi looked at Dou Yan with a look of shock, confirming what he said again and again, and then looked at her strange brother.
Dou Yan asked: "Brother, where do you think Shu Shu School is?"
Dou Yi said without hesitation: "Of course it's a place to study."
Dou Yan asked again: "Then why study?"
Dou Yi still said without any hesitation: "Be sensible and wise."
Coming from a family of education, this is almost like an ancestral precept.
Dou Yan was silent for a while, and then said: "In addition to managing Kaifeng University these years, I also have some elementary schools. Brother, do you know that children today are amazing. At the age of eight, everyone can recite multiplication tables, and at the age of nine,
They can calculate addition, subtraction, multiplication and division, and those who are a little more agile can even do mental arithmetic. How could you say that we were able to do this back then? After all, it is the Four Books and Five Classics that make people
Wisdom, or mathematics?"
Dou Yi was in a high position and was in charge of everything. She didn't understand these situations, so she asked with emotion: "Is this really true?"
Dou Yan nodded heavily and said, "I have done a special survey and found that children with excellent math scores have much faster thinking than those who study the Three Character Classic and the Thousand Character Classic. These children have a promising future.
Over the years, I have been engaged in education and have been studying the thoughts revealed by His Majesty. I have discovered many novel things that are not found in the books of Confucius and Mencius. However, the existence of this knowledge has brought about earth-shaking changes to the world, especially mathematics.
"The most."
"Brother, if His Majesty hadn't emphasized the importance of mathematics and forcibly promoted mathematics by using 'number' as one of the six arts, what would be the situation today?"
"I have been studying mathematics these years and found that the profoundness of mathematics is far beyond what the Four Books and Five Classics can compare with..."
"Shut up!" Dou Yi was so angry that her body trembled slightly and she said sternly: "Do you know what you are talking about?"
Dou Yan said without fear: "Of course I know, I am still very clear. I have also been confused before, but looking at the students who have changed and the world becoming more and more prosperous, I am now more awake than anyone else." He looked at
His brother said word for word: "Mathematics is no less important than the Four Books and Five Classics, or even the Tao of Confucius and Mencius. The Tao of Confucius and Mencius teaches people to understand reason, but mathematics can open up wisdom."
Dou Yi slammed the table in front of her, unable to say a word.
Dou Yan smiled happily and said: "Brother, please don't think that you are just a fool. You are a fan of the authorities. What a noble person you are. In the past, you regarded money as dirt and despised the pursuit of profit by businessmen. But now? You only focus on research.
In business and politics, I think about how to save money all day long..."
